Abstract: A trailer wall construction having reduced weight. A trailer wall construction includes a spherical shaped corner at a juncture of three walls. Each of the walls includes at least one panel having spaced apart inner and outer shells. Another trailer wall construction includes a generally vertically extending front or side wall and a floor. The floor and front or side wall each includes at least one panel comprising spaced apart inner and outer shells. A curved connector connects a lower edge of the front or side wall to an edge of the floor. Yet another trailer wall construction includes a wall with panels attached to one another along opposing edges of the panels, each of the panels including spaced apart inner and outer shells. One connector is attached to each of the panels along a third edge. Another connector is attached to each of the panels along a fourth edge.

Abstract: A trailer having sides with a combination of extruded panel and sheet material. A trailer wall construction for use as part of a trailer assembly includes at least one panel comprising spaced apart inner and outer shells, and at least one sheet. An edge of the sheet is attached to an edge of the panel. Another trailer wall construction includes a vertical side having a lower portion with spaced apart inner and outer shells, and an upper portion with only a single sheet thickness.
